PURPOSE:To enhance the discharging performance of a cell and allow it to endure long time service and storage by forming an oxygen selective penetration film as a Co porphyrin complex film or a mixture film of this material and polytrymethylsilylpropine, and furnishing this penetration film between the air take in side of a gas diffusion electrode and the inside of a battery vessel. CONSTITUTION:A composite film used 11 shall be of oxygen selective penetration type consisting in a Co porphyrin complex film or a mixture film of this substance and polytrimethylsirylpropine. This is installed between a porous film 2 and a porous body to perform oxygen dispersion in such as arrangement that the side containing the complex body confronts the side with air intake hole 3. This increases the oxygen penetrating speed as a trait of battery, improves the effect of shutting off water vapor and/or CO2 gas from the atmosphere, and enhances the high load discharging performance required of a practical battery as well as the performance in the case of long time discharge in an atmosphere with high or low humidity. |
